MT4 vs MT5 at FTMO: Which Platform to Pick (2026)

MT4 vs MT5 at FTMO is a straightforward comparison in 2026: MT5 is the modern default, and MT4 is the legacy path that remains valid only for traders with existing expert advisors they have not yet migrated. Both platforms sit inside FTMO's three-platform lineup alongside cTrader, but the directional momentum is clear. Every recent product expansion at FTMO lands on MT5 first, and the August 2025 US relaunch via the OANDA partnership is MT5-only. New traders should pick MT5. EA traders weighing migration need to understand exactly what changes before they port.

Paul has traded FTMO for roughly four years and withdrawn $15K+ in payouts across multiple accounts. FTMO was one of his first prop firms as a European trader. The platform-choice decision he has watched evolve across the industry is the same one this article walks through: MT4 was the standard for years, MT5 is now clearly the successor, and the migration question is the only real nuance left.

This article is part of the FTMO Platforms cluster and links across to the FTMO Rules Overview, the FTMO Accounts Overview, and the FTMO 1-Step Challenge pages for context on rules and account structure. The FTMO FAQ collects all remaining questions.

MT4 vs MT5 at FTMO — which is better?

MT5 is the better platform for most FTMO traders as of May 2026. It offers a broader instrument set, a more capable backtest engine, modern MQL5 algorithmic infrastructure, and native depth-of-market in the order book panel. The August 2025 US relaunch via the OANDA partnership is built entirely on MT5, making it the only MetaQuotes route available to US-based traders.

MT4 is not broken or removed. FTMO still fully supports MT4, with active execution, active payouts, and active trader support. The legacy framing is forward-looking rather than a deprecation warning: MT4 capability at FTMO is stable; new capability is shipping on MT5.

The decision comes down to a single question: do you have a profitable MQL4 expert advisor that you have not yet ported to MQL5? If yes, MT4 is the right short-term choice while you build and validate the MT5 port in parallel. If no, MT5 is the right choice without qualification.

Platform choice does not change FTMO's rules or pricing. The 1-Step Challenge runs the same 10% profit target, 3% daily loss limit, and 10% trailing maximum loss on MT4 and MT5 equally. The 2-Step Challenge runs the same Phase 1 and Phase 2 targets and drawdown rules on both. Pricing depends on account size and evaluation type, not on platform. Profit splits and payout frequency are identical across the entire FTMO platform lineup.

What can MT5 do that MT4 can't?

MT5 has four concrete advantages over MT4 at FTMO that are relevant to most traders.

Broader instrument coverage. FTMO's MT5 symbol list is larger than its MT4 list. New instruments, particularly newer crypto CFDs, regional index CFDs, and additional commodity pairs, tend to land on MT5 first, sometimes without appearing on MT4 at all. The core forex majors and minors, gold, silver, oil, and the main global equity indices are available on both platforms. Traders who work primarily in EUR/USD, GBP/USD, USD/JPY, and similar tier-1 pairs will not notice the difference in practice. Traders who venture into less common instruments should verify availability on MT5's symbol list specifically, since MT4's subset may be missing the symbol they need.

Multi-symbol tick-data strategy tester. The MT4 strategy tester runs a single symbol at a time, uses modelled ticks by default (which are interpolations, not real tick history), and does not support walk-forward optimization or cloud-distributed backtesting. The MT5 strategy tester runs multi-symbol tests simultaneously, supports actual tick data for all available symbols, and includes walk-forward optimization and cloud optimization runs. For EA developers building FTMO-compliant systems, the quality difference is material. The FTMO 1-Step Challenge has the Best Day Rule consistency constraint: no single profitable day can exceed 50% of total positive days' profit. Accurately modelling that constraint requires examining daily-PnL distributions across a multi-year tick-level data history, which the MT5 strategy tester handles and the MT4 tester handles poorly.

More order types. MT5 supports Buy Stop Limit and Sell Stop Limit orders natively, which allow traders to place a pending stop that only activates when price reaches a specified level, at which point it becomes a limit order rather than a market order. MT4 does not have these order types; MQL4 developers who need that logic have to implement it programmatically, which introduces execution complexity and potential slippage. For traders who place complex pending orders around news events or opening auctions, the native MT5 order types eliminate several lines of EA logic.

Netting-mode account support. MT4 accounts at FTMO are hedging-mode: multiple positions on the same symbol can be open simultaneously in opposite directions. MT5 at FTMO supports netting-mode configuration, where a new position in the opposite direction closes or partially closes the existing position on the same symbol. For purely discretionary traders, the distinction rarely matters. For EA developers building systems that explicitly net against existing positions, the MT5 netting-mode account is architecturally cleaner than the hedging-mode workaround required on MT4.

What can MT4 do that MT5 can't?

MT4's single genuine advantage at FTMO is MQL4 expert advisor compatibility.

MQL4 is the programming language embedded in MetaTrader 4. Expert advisors written in MQL4 run natively on FTMO MT4 accounts without modification. Traders who built and validated profitable MQL4 EAs over the past decade, and who have not yet ported those systems to MQL5, can continue running them on FTMO MT4 with full platform support.

MT5 does not run MQL4 code. MQL5 is a different language with different function libraries, different position-management semantics, and different strategy-tester behaviour. A profitable MQL4 EA does not simply recompile on MT5; it requires a deliberate migration.

There is no other meaningful area where MT4 outperforms MT5 at FTMO. The older charting engine, the smaller indicator library, and the weaker strategy tester are not advantages. They are legacy characteristics that the MT4 user base tolerates specifically because of the EA compatibility argument.

One narrow secondary consideration: some third-party indicator vendors still distribute MT4-only products, particularly niche volume-profile tools and market-internals panels built in the early 2010s. If your specific workflow depends on an MT4-only vendor product that has never been ported, MT4 gives you access to it. This is a diminishing category as most serious vendors now support both versions, but it is worth verifying before committing.

How do instrument lists differ?

FTMO covers forex, indices, commodities, metals, and crypto across both platforms. FTMO is a forex and CFD firm with no futures offering; this is an important boundary condition for traders coming from US futures-focused platforms like Topstep or Apex. The FTMO Platforms overview covers the full asset-class picture in detail.

Within the CFD universe, MT5's symbol list at FTMO is a superset of MT4's. The pattern documented since 2024 is that new symbol additions land on MT5 first, sometimes permanently. The practical instrument-list difference by category looks like this:

Forex: Majors, minors, and most exotics are available on both platforms. No meaningful difference for standard forex trading.

Indices: Core global equity indices (S&P 500 CFD, DAX, FTSE, Nikkei, Nasdaq) are on both platforms. Newer regional index additions and smaller-cap index CFDs are more likely to appear exclusively on MT5.

Metals: Gold (XAUUSD) and Silver (XAGUSD) are on both platforms. Platinum and palladium CFDs are more reliably available on MT5.

Commodities: Oil (WTI, Brent) and natural gas are on both platforms. Softs and agricultural commodity CFDs are more likely to appear only on MT5.

Crypto: Bitcoin, Ethereum, and Litecoin CFDs are the most universally available. Newer crypto additions, including additional altcoin pairs, are typically MT5-first and sometimes MT5-only.

For a scalper focusing on major forex pairs and gold, both platforms cover the entire working universe. For a multi-asset trader building a portfolio of CFD positions across indices, metals, and crypto, MT5's broader list is a meaningful practical advantage.

What about EA migration from MT4 to MT5?

EA migration from MQL4 to MQL5 is the most consequential decision for algorithmic FTMO traders, and it is non-trivial. The migration involves five categories of change.

Position management functions. MQL4 uses OrderSend, OrderModify, and OrderClose as the primary position-management functions. MQL5 replaces these with a separate trade request structure (MqlTradeRequest, PositionSelect, PositionGetDouble) that is more explicit but requires a full rewrite of the order-management layer. This is the largest code change for most EAs.

Hedging-mode to netting-mode logic. MT4 accounts are hedging-mode: the EA can hold simultaneous long and short positions on the same symbol and manage them independently. MT5 netting-mode accounts net opposing positions against each other. EAs that rely on hedging logic (for example, holding a long and a short simultaneously as part of a grid or hedge strategy) must be redesigned for MT5's netting semantics, not just recompiled.

Strategy tester calibration. The MT4 strategy tester and the MT5 strategy tester produce different backtest results for the same logic because they use different tick-generation models and different bar-indexing conventions. After porting, the MT5 backtest should be rerun on tick data from scratch to validate that the strategy's edge, drawdown profile, and daily-PnL distribution are preserved. Do not compare MT4 and MT5 backtest equity curves directly without understanding why they differ.

DLL dependencies. Some MQL4 EAs use Windows DLL files for functionality not available natively in MQL4 (for example, custom database connectors, external data feeds, or platform-integration bridges). DLLs compiled for 32-bit MT4 do not run in 64-bit MT5. The DLLs need to be recompiled for 64-bit, or the functionality needs to be rewritten natively in MQL5 using its expanded standard library.

Best Day Rule modelling. This is specific to FTMO's 1-Step Challenge. The Best Day Rule states that no single profitable day can exceed 50% of total positive days' profit. The rule does not auto-breach the account; it is a consistency constraint that FTMO uses at payout review. EA developers should model the daily-PnL distribution of their ported system on MT5 tick data specifically to verify that no single high-volatility day in the backtest history would have diluted the ratio below 50%. The MT5 strategy tester's multi-symbol tick-level accuracy makes this modelling exercise materially more reliable than it is on MT4.

The recommended transition pattern for FTMO traders is: keep the validated MT4 EA running on the live FTMO account while developing and testing the MT5 port on a separate FTMO MT5 evaluation account or demo account. Once the MT5 port has completed a full evaluation cycle on FTMO's data feed and the rules-compliance profile (including Best Day Rule distributions) is confirmed, switch the live deployment to MT5. Do not port and deploy in a single step.

How does the OANDA US-relaunch tilt the choice?

The August 2025 US relaunch is the clearest external factor pushing traders toward MT5, and it is decisive for US-based FTMO traders.

FTMO suspended US services in early 2024. The combination of MetaQuotes restricting US-based prop firm access to its platforms and the post-MyForexFunds CFTC regulatory environment made continued US operations untenable. For roughly 18 months, US traders had no FTMO route.

The relaunch in August 2025 came through the OANDA partnership. OANDA is one of the oldest regulated forex brokers globally, with US, UK, EU, and Asian regulatory footprints. FTMO acquired OANDA in a deal announced in February 2025 and completed in December 2025; FTMO founders Otakar Šuffner and Marek Vašíček became OANDA co-CEOs in March 2026. US traders re-enter FTMO through OANDA's US-registered entity, which handles the funded rewards stage, while FTMO handles the evaluation stage.

The platform underneath the US relaunch is MT5 specifically. FTMO became the first prop firm offering MT5 to US-based traders as a result. MT4 access is not part of the US re-entry path.

For US-based EA developers who built profitable MQL4 systems, this is a firm deadline on the migration question: you cannot run those systems on FTMO without completing the MT5 port. There is no MT4 workaround or exception for US traders under the current OANDA-FTMO structure.

For non-US traders, the OANDA-MT5 arrangement is mostly invisible at the trader-facing level. The standard FTMO entry through ftmo.com still presents all three platforms (MT4, MT5, cTrader). The OANDA acquisition shows up as a trust signal and as backend infrastructure rather than as a different signup flow. Non-US traders are not forced to change their platform choice as a result of the acquisition.

The OANDA acquisition's broader significance for FTMO's trustworthiness is covered in the FTMO Accounts Overview and connects to the larger picture in the FTMO Rules Overview. For the platform-choice question specifically, the US-relaunch data point is the most actionable: if you are a US trader, the platform choice is MT5, full stop.

Should new FTMO traders pick MT4 or MT5?

New FTMO traders should pick MT5.

The case is not close. MT5 is where FTMO's product expansion is heading, it has the broader instrument set, the better backtest engine, the modern algorithmic language, and the only MetaQuotes route to US traders. There is no disadvantage to MT5 for a trader arriving without a pre-existing MT4 EA investment.

The cleaner question for a new trader is actually MT5 versus cTrader. Both are modern platforms with full instrument coverage at FTMO. MT5 is the better choice for algorithmic traders who want to write EAs or backtest systematically. cTrader is the better choice for discretionary scalpers who want the most polished native Level-2 depth-of-market display. The FTMO Platforms overview walks through that MT5-versus-cTrader split in detail.

For purely discretionary traders who do not write EAs and do not specifically need a DOM panel, MT5 is the safe default: it covers the full instrument list, FTMO is clearly expanding toward it, and the ergonomics are competitive with cTrader for most non-DOM workflows.

For traders using FTMO's 2-Step Challenge path specifically, platform choice interacts with consistency requirements in the same way as the 1-Step: neither the 2-Step's lack of a Best Day Rule nor the 1-Step's Best Day Rule changes which platform to pick, but they both make the MT5 strategy tester's higher accuracy more valuable if you are running any sort of systematic testing alongside your discretionary trading.

Paul's four-year FTMO experience, with $15K+ withdrawn across multiple accounts on the 1-Step Challenge in $50K and $100K sizes, was built on a scalping style where platform ergonomics are more about comfort than fundamentals. The new-trader recommendation is MT5 regardless of style because it removes all the forward-looking risk of being on the legacy path.

When does MT4 still make sense?

MT4 still makes sense at FTMO in a narrow and shrinking set of cases.

Case 1: You have a profitable MQL4 EA in live deployment. If your EA is running on FTMO MT4, passing evaluations, and producing payouts, there is no urgency to migrate. The migration should happen on a separate development track, validated on tick data, before being moved to live. Stay on MT4 while you build the MT5 port.

Case 2: Your MT5 port has not yet been validated on FTMO's feed. Even if the migration code is complete, the MT5 port should complete a full evaluation cycle on a separate FTMO account, or at minimum a multi-month demo period on FTMO's MT5 data feed, before replacing the live MT4 deployment. The difference between backtested behaviour and FTMO-feed live behaviour can be meaningful for scalpers and for systems that trade around news events.

Case 3: Your workflow depends on an MT4-only vendor indicator. If there is a specific third-party tool, volume-profile panel, or market-internals display that is distributed as MT4-only and has no MT5 equivalent, MT4 lets you keep using it. Audit your tooling first: most serious vendors have MT5 versions. If yours does not, either work with the vendor on an MT5 port or find an equivalent MT5 tool before switching.

Not a valid case: familiarity. If the only reason to stay on MT4 is comfort with the interface, that is a solvable problem rather than a constraint. MT5's interface is closely analogous to MT4's. The chart objects, indicators, and order-management workflow are structurally similar. Familiarity with MT4 does not meaningfully extend the switchover time for a discretionary trader.

Not a valid case: "MT4 is more stable." Both platforms are mature and stable at FTMO. MT4 being older does not make it more reliable on FTMO's execution layer. The execution infrastructure is FTMO's, not MetaQuotes'. Stability is determined by FTMO's servers and connectivity, not by which front-end client version you run.

The timeline on MT4's long-term status at FTMO is not publicly announced. MetaQuotes, the platform vendor, has been progressively deemphasising MT4 licensing since the early 2020s, and some brokers have already announced MT4 sunset timelines. FTMO has made no such public statement as of May 2026, and MT4 remains fully supported. The prudent approach is to treat MT4's continued availability as indefinitely stable while actively building the MT5 transition on a secondary track.

The bottom line

MT4 vs MT5 at FTMO resolves clearly in 2026: MT5 is the right choice for new traders, and MT4 is the right choice only for traders who are actively managing a profitable legacy MQL4 EA deployment.

MT5 wins on every dimension except backward compatibility with MQL4. Broader instruments, better backtest engine, modern algorithmic language, native depth-of-market, more order types, netting-mode support, and the only MetaQuotes route for US traders via the OANDA partnership: every forward-looking advantage sits on MT5. FTMO's $329M revenue base and December 2025 OANDA acquisition completion mean this is a firm with the financial infrastructure to keep both platforms running long-term, but new product capability lands on MT5 first.

MT4 stays valid specifically because of the MQL4 EA library that a generation of prop traders built over the 2010s. If you have systems in that library that are producing payouts on FTMO, migrating them is a risk management exercise rather than an urgent upgrade. The migration path (MQL4 to MQL5, hedging-mode to netting-mode, strategy-tester recalibration on tick data) is non-trivial but well-documented, and the FTMO-specific consideration (Best Day Rule modelling on the 1-Step Challenge) is easier to validate on MT5's tick-data tester than on MT4's older engine.

For traders building new systems at FTMO in 2026, MT5 is the starting point. For traders already running MT4 systems profitably, stay on MT4 through the transition, build the MT5 port on a separate track, and migrate when the port is validated. For US traders, the choice is already made: MT5 is the only available route.

Frequently Asked Questions

Is MT4 or MT5 better at FTMO?

MT5 is better for most traders. It has a broader instrument set, a modern MQL5 backtest engine with tick-data support, and is the only route available to US traders via the August 2025 OANDA partnership. MT4 stays valid specifically for traders with profitable MQL4 expert advisors that have not been ported to MQL5.

What can MT5 do that MT4 can't at FTMO?

MT5 at FTMO offers a broader instrument list (more index CFDs, more crypto pairs), a multi-symbol tick-data strategy tester, native depth-of-market in the order book panel, more order types (including Buy Stop Limit and Sell Stop Limit), and netting-mode account support. The MQL5 strategy tester also supports walk-forward optimization and cloud-distributed backtesting, none of which are available in the MT4 strategy tester.

What can MT4 do that MT5 can't at FTMO?

MT4's main advantage at FTMO is MQL4 EA compatibility. Traders with profitable MQL4 expert advisors that rely on hedging-mode logic or Windows DLL dependencies can run them on MT4 without modification. MT5 requires MQL5, and the migration involves rewriting hedging-mode calls to netting-mode semantics. Beyond EA compatibility, there is no area where MT4 outperforms MT5 at FTMO.

Are the instrument lists different between MT4 and MT5 at FTMO?

Yes. FTMO's MT5 instrument list is broader than its MT4 list. New instruments, particularly newer index CFDs and crypto pairs, tend to land on MT5 first and sometimes do not appear on MT4 at all. Forex majors, minors, the headline metals, and core commodities are available on both platforms. Multi-asset traders expanding into less common pairs should verify symbol availability on MT5 specifically.

How does EA migration from MT4 to MT5 work at FTMO?

Migration requires converting MQL4 source code to MQL5. The core logic changes involve rewriting hedging-mode position-management calls to MT5's position and deal functions. Systems using Windows DLL dependencies need those DLLs recompiled or replaced. The MT5 strategy tester behaves differently from MT4's, so post-migration backtests should be run on tick data before live deployment. A two-track setup (MT4 live while testing the MT5 port in parallel) reduces risk during the transition.

Does the OANDA US relaunch change the MT4 vs MT5 choice?

Yes, decisively for US traders. FTMO's August 2025 US relaunch via the OANDA partnership runs on MT5 only. US traders cannot access FTMO on MT4. If you are a US-based EA developer with MQL4 systems, you must complete the MT5 port before trading FTMO. Non-US traders are not affected by this restriction.

Should new FTMO traders pick MT4 or MT5?

New traders should always pick MT5. The broader instrument set, better backtest engine, modern MQL5 language, and FTMO's US-relaunch architecture all point in that direction. MT4 is a legacy choice justified only by existing EA investment in MQL4.

When does MT4 still make sense at FTMO?

MT4 still makes sense when you have a profitable MQL4 expert advisor that has been tested and validated on FTMO's feed and you do not yet have a stable MT5 port. Running MT4 for the live account while porting in parallel on MT5 is the safest transition pattern. Once the MT5 port is validated, there is no continuing reason to stay on MT4.

Does platform choice affect FTMO's rules or pricing?

No. The 1-Step Challenge runs the same 10% target, 3% daily loss, and 10% trailing max loss on both MT4 and MT5. The 2-Step runs the same Phase 1 and Phase 2 targets and drawdown rules. Pricing, profit splits, payout frequency, and the Scaling Plan are identical across MT4, MT5, and cTrader. Platform is an ergonomics and tooling decision, not a rules or cost decision.

Is the MT5 backtest engine better than MT4's for FTMO strategy development?

Yes, significantly. MT5's strategy tester supports tick-data backtests using MQL5, multi-symbol testing, walk-forward optimization, and cloud-distributed optimization. MT4's strategy tester is single-symbol, lower accuracy, and does not support walk-forward or cloud runs. EA developers building FTMO-compliant systems — especially systems that need to model the 1-Step Best Day Rule over a multi-year data history — get materially better development tooling on MT5.

Can I switch from MT4 to MT5 mid-evaluation at FTMO?

Platform selection happens at account creation. Switching platforms mid-evaluation is not a standard FTMO workflow and in practice means opening a new evaluation account. If you started on MT4 and want to move to MT5, the cleanest path is completing the current MT4 evaluation and opening a fresh MT5 evaluation. Verify with FTMO support before attempting mid-cycle platform changes.

Does FTMO have more instruments on MT5 than MT4?

Yes. FTMO's MT5 symbol list is broader than MT4's. New instrument additions, including newer crypto CFDs and regional index CFDs, typically land on MT5 first. The core forex majors and minors, gold, silver, oil, and the main global indices are available on both platforms. Traders who trade primarily major forex pairs will not notice a practical difference; traders in more niche instruments should check MT5's symbol list specifically.
